From: Richard Genoud Date: Tue, 28 Oct 2025 07:35:05 +0000 (+0100) Subject: mtd: rawnand: sunxi: introduce reg_spare_area in sunxi_nfc_caps X-Git-Tag: v6.19-rc1~153^2^2~9 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6208274d0a27b81ae5425c819810fcd7bf89636a;p=thirdparty%2Fkernel%2Flinux.git mtd: rawnand: sunxi: introduce reg_spare_area in sunxi_nfc_caps The H6/H616 spare area register is not at the same offset as the A10/A23 one, so move its offset into sunxi_nfc_caps. No functional change.
